SANDPAPER HOLDER Filed July 9, 1928 INVENTOR zZeder/c/f 6: Par/w M ATTORNEY Patented Sept. 19, 1933 Q 'SANDPAPER HOLDER Frederick 0. Parks, Kennydale, Wash. Application July 9, 1928. Serial No. 291,196 e V 3 Claims." c1. 51 "1s'z) This invention relates to a holder for sand paper, emery cloth and the like for use more especially in cleaning eggs although it is applicable for smoothing and polishing wood.

The object of the invention is to provide animproved holder of this character which is of sim* ple and inexpensive construction, and which is more eflicient and convenient to use than other holders known to me.

The invention consists in the novel construction, adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawing,

Figure 1 is a perspective view of a holder embodying the invention with a sheet of abrading material applied thereto;' Figure 2 is a perspective view of the holder shown separately; and Fig. 3 is an end elevation of one of the clamping devices shown in Fig. 1.

In carrying out my invention, there is provided a body5, or block as hereinafter termed, which may be made of wood or other suitable material. The block is of substantially the shape in which it is illustrated-that is, with parallel plane end surfaces 6 and 7 and curvilinear in transverse section to aiford a convex upper surface 8, a concave under surface 9 between two rounded wing elements 10 located below concavities 11 in the opposite sides of the block. The block is also provided with grooves or slots 12, one in each side extending from the respective concavities 11.

Said grooves are desirably of rectangular shape in transverse section, with parallel upper and lower surfaces 13 and 14 as indicated in Fig. 2. As shown, the grooves 12 are in'a horizontal plane and extend longitudinal the entire length of the block.

15 represents a layer of rubber, felt, or other suitable resilient or yieldable material which is glued or otherwise secured against the concave under surface 9 of the block.

' 16 represents a sheet of sand papenor of fabric, coated with an abrasive material such as pulverized emery.

For use in cleaning eggs, the sheet of sand paper, or its equivalent, is applied to the block 5 as shown in Fig. 1 so as to extend as at 16 across the cavity in the bottom of the block and thence about the wings 10 and into the grooves 12 wherein the side edges of the sheet are respectively secured by means of keys 17.

Each of said keys is formed of a strip of sheet metal of a length equal to the length of the block, or nearly so, and is folded laterally to the shape in which shown in Fig. 3, to provide a loop 7 pressed into contacting and lower facing surfaces of each 18 with two, leaf elements 19 which diverge slightly toward their free edges 20. I

For use ,the keys are shoved into the'grooves 12 The block is advanard sizeof sand paper when thesame is em: ployecl about the under portion of the block as shown in Fig. l.

For cleaning an egg, it is held in one hand of the operator while with his other hand he grasps the block from the top, the rounded upper portion of the block bearing againstthe palm of the hand and the fingers and thumb engage the same in the side cavities 11. In such .egg cleaning operation, the egg andthetool are manipulated in a manner to treat the egg at the soiled places by local abrading actions.

The layer 15 safeguards the eggs from being injured in case of excessive flexing of the sandpaper into the cavity in the underside of the 7 body.

While the, invention is intended primarily as an egg cleaning tool it is not limited thereto, but

'may be used for other sand papering purposes as, for example, in smoothing or cleaning wood work.

What I claim, is,-'

1. In a holder for an bination with a block, the sides of which provide, approximately medially of .the block height, lonreceive lateral edges of a strip of abrasive material extending from one slot to the other about a pair of normally open leaves'inter-connected by a common spring loop, said leaves being comengagement to locate outer surfaces parallel, one. to theother, for wedging said leaves into the slot. 2. In a holder for an abrasive strip, the combination with a block providing longitudinally disposed slots along sides of the same, said slots serving to receive lateral edges ofa strip of abrasive material extending from one slot to the other abrasive strip, the come about the underneath face of the block, the'upper of said slots being parallel, of resilient keys formedfrom a 9ogitudinally disposed slots, said, slots serving to into the slot.

pieceof spring metal to provide normally open leaves interconnected'by a common loop portion for detachably securing the abrasive strip edges in the slots, said leaves being adapted to be compressed to locate outer surfaces of the same par allel; one to, the other, for wedging the leaves 3. In a sandpaper a block, the. lowe'r' and upperpo'ift'idfis' fesplc: tively of which provide a Working face and a hand grip, the sides of said block between said upper and lower portions being longitudinally holder, the combination with slotted for the reception of lateral edges of a strip keys in the v slots yvith I loops 'affor'd'hg contact of sandpaper passed the working face of the block, of resilient keys for detachably securing said lateral edges of the sandpaper in the slots, said'keys being formed.

to present a pair of normally open spring leaves interconnected by a common 100p, said leaves being adapted to be compressed into engagement, one leaf with a companion leaf, for inserting the the springaction of the of the lower leaf of each key against'the sandpaper. V
